Blood component measurement device and tip for blood measurement

Abstract

A blood component measurement device has a puncturing unit provided inside a housing and having a puncture needle; a button unit for advancing and retreating the puncture needle; a contact mechanism coming into contact with the skin of a person to be measured; and a holder for displaceably holding the puncturing unit. The blood component measurement device also has an introduction section at the substantially center of a contact member. After the skin is punctured by the puncture needle provided at the substantially center of the mechanism, the introduction section introduces blood to testing paper when the contact member of the contact mechanism is displaced in a sliding manner along a guide member.

AI Technical Summary

Benefits of technology

The present invention provides a blood component measurement device with a tip for blood measurement that can efficiently introduce blood to the measurement unit with a minimum amount of blood. The device has a puncture needle that can be advanced and retreated, a contact section that comes into contact with the skin, and a blood introduction section that communicates with the measurement unit. A guide section holds the contact section displaceably in a direction at a predetermined angle to facilitate puncturing and blood introduction. The device can be easily replaced after measurement of a blood component is completed. The technical effects of the invention include efficient blood introduction, accurate blood measurement, and convenient and easy replacement of the device components.

Problems solved by technology

Besides, according to the related art as above-mentioned, the configuration wherein the puncture needle is disposed in a capillary tube causes difficulties in design, layout or the like of the measurement unit for measuring a component of blood, and makes it difficult to achieve the desired measurement by use of a measurement device simple in configuration.
